In this exclusive sneak peek from Wednesday's episode (9/8c on NBC), Rollins comes home to find Kim being sexually assaulted by someone carrying a gun. Rollins takes matters into her own hands to protect her now-pregnant sister and soon enough, cops are swarming her apartment. So what did Rollins do? And will Benson (Mariska Hargitay), Capt. Cragen (Dann Florek) and the rest of the SVU squad be able to help her? One thing is for sure — it's never a good sign when Benson is calling Rollins by her first name.
